Sutera plant named &#39;volsut 2302&#39;

ABSTRACT

A new and distinct cultivar of  Sutera  plant named ‘VOLSUT 2302’, characterized by its compact, mounding and trailing plant habit; vigorous growth habit; freely branching habit; early and freely flowering habit; and relatively large white-colored flowers.

Botanical designation: Sutera diffusus.

Cultivar denomination: ‘VOLSUT 2302’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sutera plant, botanically known as Sutera diffusus and hereinafter referred to by the name ‘VOLSUT 2302’.

The new Sutera plant is a product of a planned breeding program conducted by the Inventor in Muenster, Germany. The objective of the breeding program is to create new compact and freely branching Sutera plants with numerous large flowers.

The new Sutera plant originated from an open-pollination in 2012 in Muenster, Germany of an unnamed proprietary selection of Sutera diffusus, not patented, as the female, or seed, parent with an unknown selection of Sutera diffusus as the male, or pollen, parent. The new Sutera plant was discovered and selected by the Inventor as a flowering plant from within the progeny of the stated open-pollination in a controlled greenhouse environment in Muenster, Germany in 2013.

Asexual reproduction of the new Sutera plant by terminal cuttings in a controlled greenhouse environment in Muenster, Germany since 2014, has shown that the unique features of this new Sutera plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Sutera have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘VOLSUT 2302’. These characteristics in combination distinguish ‘VOLSUT 2302’ as a new and distinct Sutera plant:

-   -   1. Compact, mounding and trailing plant habit.     -   2. Vigorous growth habit.     -   3. Freely branching habit.     -   4. Early and freely flowering habit.     -   5. Relatively large white-colored flowers.

Plants of the new Sutera can be compared to plants of the female parent selection. Plants of the new Sutera differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Sutera are not as trailing as plants of the         female parent selection.     -   2. Plants of the new Sutera are more freely flowering than         plants of the female parent selection.     -   3. Plants of the new Sutera have larger flowers than plants of         the female parent selection. Plants of the new Sutera can be         compared to plants of the Sutera cordata ‘SBAWHO3-2’, disclosed         in U.S. Plant Pat. No. 23,881. In side-by-side comparisons         conducted in Muenster, Germany, plants of the new Sutera differ         primarily from plants of ‘SBAWHO3-2’ in the following         characteristics:     -   1. Plants of the new Sutera are not as trailing as plants of         ‘SBAWHO3-2’.     -   2. Plants of the new Sutera have larger and darker green-colored         leaves than plants of ‘SBAWHO3-2’.     -   3. Plants of the new Sutera have slightly larger flowers than         plants of ‘SBAWHO3-2’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Sutera plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Sutera plant.

The photograph is a side perspective view of a typical flowering plant of ‘VOLSUT 2302’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown during the spring in 12-cm containers in a glass-covered greenhouse in Muenster, Germany and under commercial practices typical of commercial Sutera production.

During the production of the plants, day temperatures ranged from 16° C. to 25° C., night temperatures ranged from 14° C. to 16° C. and light levels ranged from 5 to 65 klux. Plants were pinched two to three weeks after planting and were six months old when the photograph and the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, Sixth Edition, except where general terms of ordinary dictionary significance are used.
